FIELD OF TECHNOLOGY

The present application relates to a warp knitted fabric and a method of manufacturing warp knitted fabrics.

BACKGROUND

In the contemporary fashion market, designers never stop looking for new ideas in making fascinating, innovative and versatile products to catch the eyes of their potential customers, wherein the shine of various sorts plus the garment of multifunctional features contributes to the product by adding remarkably high extra value.

We have now developed a warp knit fabric that provides not just an unusual satin-look luster and smoothness on the commercial face of the fabric but a strong shaping power with good anti-snagging and gripping attributes.

Snagging, as we know, is an inherent enemy of all types of satin fabric. The reason is simply that the highly oriented yarns of long yarn length, aligning on the surface of the fabric, provides on one hand a high degree of mirror-like reflection of light from the fabric surface, but on the other hand a high degree of snagging attribute as well.

This fabric is made from a Tricot type warp knitting machine with the typical looping movements of the guide bars and the exclusively designed knitting parameters. It can satisfy needs from different aspects such as the unconventional sheen and smoothness of different sorts, anti-snagging attribute, good supporting power with high stretching recovery and gripping with secured touch.

There exist various end uses for this type of fabric such as shapewear, high power garments, sportswear, and intimate apparels, strapless garments on evening gowns or wedding dresses, swimsuits and so on.

The above description of the background is provided to aid in understanding a warp knitted fabric, but is not admitted to describe or constitute pertinent prior art to the warp knitted fabric disclosed in the present application, or consider any cited documents as material to the patentability of the claims of the present application.

Although the warp knitted fabric disclosed in the present application is shown and described with respect to certain embodiments, it is obvious that equivalents and modifications will occur to others skilled in the art upon the reading and understanding of the specification. The present application includes all such equivalents and modifications, and is limited only by the scope of the claims.

DETAILED DESCRIPTION

Reference will now be made in detail to a preferred embodiment of the warp knitted fabric disclosed in the present application, examples of which are also provided in the following description. Exemplary embodiments of the warp knitted fabric disclosed in the present application are described in detail, although it will be apparent to those skilled in the relevant art that some features that are not particularly important to an understanding of the warp knitted fabric may not be shown for the sake of clarity.

Furthermore, it should be understood that the warp knitted fabric disclosed in the present application is not limited to the precise embodiments described below and that various changes and modifications thereof may be effected by one skilled in the art without departing from the spirit or scope of the appended claims. For example, elements and/or features of different illustrative embodiments may be combined with each other and/or substituted for each other within the scope of this disclosure and appended claims.

The warp knitted fabric of the present application can be manufactured by a Tricot type warp knitting machine with at least 2 guide bars, wherein at least one of the guide bars at the front side of the machine is designed for lapping non-elastomeric yarns on the knitting needles to perform the knitting action, known as a fabric or loop formation process, and at least one of the guide bars at the rear side of the machine is designed for lapping elastomeric yarns on the knitting needles to perform knitting action. The lapping motion of guide bars at front precedes that of the guide bars at rear but the knitting action for all guide bars takes place at once.

Considering a machine of two guide bars, the guide bar at front, named “guide bar 1”, can be made for lapping non-elastomeric yarns on the knitting needles, and the guide bar at rear, named “guide bar 2”, can be made for lapping elastomeric yarns on the knitting needles at a lagged period of time against that of “guide bar 1” to perform the same knitting action all together. Yarns can be threaded through the guide needles of the two guide bars and knitted in different stitch patterns to form the desired knitted fabric.

According to an embodiment of the present application, a non-elastomeric yarn 10 may be threaded through the guide needles of “guide bar 1” and knitted in a close 2×1 stitch pattern. FIG. 1 shows a lapping diagram and a chain notation of the non-elastomeric yarn 10 threaded through the guide needles of “guide bar 1” and knitted in a close 2×1 stitch pattern. The non-elastomeric yarn 10 may be nylon, or any other suitable non-elastomeric yarns. A loop structure of the technical back of warp knitted non-elastomeric yarns 10 is shown in FIG. 2.

According to an embodiment of the present application, an elastomeric yarn 20 may be threaded through the guide needles of “guide bar 2” and knitted in an open 1×1 pillar stitch pattern. FIG. 3 shows a lapping diagram and a chain notation of the elastomeric yarn 20 threaded through the guide needles of “guide bar 2” and knitted in an open 1×1 pillar stitch pattern. The elastomeric yarn 20 may be spandex, or any other elastic yarn having substantially the same characteristics of spandex. A loop structure of the technical back of warp knitted elastomeric yarns 20 is shown in FIG. 4.

According to an embodiment of the present application, the method of threading for both non-elastomeric and elastomeric yarns 10, 20 is full threading. The term “full threading” can be considered as one of the threading methods for the guide bar(s) that allows all knitting needles of the machine to lap with a yarn of a particular type from the corresponding guide needles of one or more threaded guide bars.

According to an embodiment of the present application, there may be formulated effective ranges of yarn runner length, in the unit of millimeter per rack, of the non-elastomeric and elastomeric yarns 10, 20 against the machine gauge, ranged inclusively from 28 needles per inch through 50 needles per inch, of the Tricot type warp knitting machine.

According to an embodiment of the present application, there may be formulated effective ranges of aggregate linear mass density, in the unit denier, of the non-elastomeric and elastomeric yarns 10, 20 against the machine gauge, ranged inclusively from 28 needles per inch through 50 needles per inch, of the Tricot type warp knitting machine.

The warp knitted fabric may be composed of the non-elastomeric yarns 10 such as nylon or any other suitable non-elastomeric yarn of proper types and fineness, and elastomeric yarns 20 such as spandex of different elasticity and fineness. By using a Tricot type warp knitting machine, one can produce high-end warp knitted fabrics for garment products meeting different elasticity and weight requirements for both men and women.

The warp knitted fabric of the present application is suitable for many types of high-end underwear and clothing such as panties, brassieres, shapewears, bodysuits, sportswear, strapless evening gowns or wedding dresses, swimsuits and so on.

To manufacture the warp knitted fabrics of the present application, an operator may need to follow the steps of:

-   1. selecting an appropriate machine gauge of the Tricot type warp     knitting machine based on the required fabric weight in the unit of     gram per square meter (for example one may use the machine gauge of     40 needles per inch to knit a fabric of 154 gram-per-square meter     weight); and -   2. selecting an appropriate linear mass density of the     non-elastomeric yarn 10 with the formulated effective ranges for an     applicable yarn fineness, corresponding to the gauge of the warp     knitting machine being adopted (for example, one may use 20 denier     non-elastomeric nylon yarn if the machine gauge is 40); and -   3. selecting an appropriate linear mass density of the elastomeric     yarn 20 with the formulated effective ranges for an applicable yarn     fineness, corresponding to the gauge of the warp knitting machine     being adopted (for example, one may use 40 denier elastomeric     spandex yarn if the machine gauge is 40); and -   4. selecting an appropriate runner length of the non-elastomeric     yarn 10 with the formulated effective ranges for an applicable yarn     runner length, corresponding to the gauge of the warp knitting     machine being adopted (for example, one may use a runner length of     1030 mm per rack with a 20-denier non-elastomeric nylon yarn if the     machine gauge is 40); and -   5. selecting an appropriate runner length of the elastomeric yarn 20     with the formulated effective ranges for an applicable yarn runner     length, corresponding to the gauge of the warp knitting machine     being adopted (for example, one may use a runner length of 480 mm     per rack with a 40-denier elastomeric spandex yarn of 50%     accumulated beaming stretch if the machine gauge is 40); and -   6. knitting a set of non-elastomeric yarns 10 of substantially the     same type, fully threaded from a guide bar at the front side of the     Tricot type warp knitting machine and knitted in a close 2×1 stitch     pattern; and -   7. knitting a set of elastomeric yarns 20 of substantially the same     type, fully threaded from a guide bar at the rear side of the Tricot     type warp knitting machine and knitted in an open 1×1 pillar stitch     pattern.

To manufacture the warp knitted fabrics of the present application, an operator may need to apply the techniques of:

-   1. establishing the effective ranges of the aggregate linear mass     density, in the unit of denier, of the non-elastomeric yarn(s) 10     against the machine gauges, ranged inclusively from 28 needles per     inch through 50 needles per inch, of the Tricot type warp knitting     machine where:     -   (a) the aggregate linear mass density at a high side boundary         equals 1398×e^(−0.1×(machine gauge)) with rounded off decimal;         and     -   (b) the aggregate linear mass density at a low side boundary         equals 466×e^(−0.1×(machine gauge)) with rounded off decimal;         and     -   (c) the ranges of the effective linear mass densities are laid         between the numerical solutions, with rounded off decimal, at         the high side boundary in 1(a) and the low side boundary in         1(b). (For example, one may use a 20-denier non-elastomeric         nylon yarn if the machine gauge is ranged from 36 through 40         inclusively); and -   2. establishing the effective ranges of the aggregate linear mass     density, in the unit of denier, of the elastomeric yarn(s) against     the machine gauges, ranged inclusively from 28 needles per inch     through 50 needles per inch, of the Tricot type warp knitting     machine where:     -   (a) the aggregate linear mass density at a high side boundary         equals 1463×e^(−0.0832×(machine gauge)) with rounded off         decimal; and     -   (b) the aggregate linear mass density at a low side boundary         equals 488×e^(0.0832×(machine gauge)) with rounded off decimal;         and     -   (c) the ranges of the effective linear mass densities are laid         between the numerical solutions, with rounded off decimal, at         the high side boundary in 2(a) and the low side boundary in         2(b). (For example, one may use a 40-denier elastomeric spandex         yarn if the machine gauge is ranged from 36 through 40         inclusively.)

To manufacture the warp knitted fabrics of the present application, an operator may need to apply the techniques of:

-   1. establishing the effective ranges of the runner lengths, in the     unit of millimeter per rack, of the non-elastomeric yarn(s), fully     threaded from a guide bar at the front side of the Tricot type warp     knitting machine, against the machine gauges, ranged inclusively     from 28 needles per inch through 50 needles per inch, where:     -   (a) the yarn runner length at a high side boundary equals         4213×e^(−0.0344×(machine gauge)) with rounded off decimal;         wherein “e” equals a constant number of “2.718281828459045 . . .         ”; and     -   (b) the yarn runner length at a low side boundary equals         3447×e^(−0.0344×(machine gauge)) with rounded off decimal; and     -   (c) the ranges of the effective yarn runner length are laid         between the numerical solutions, with rounded off decimal, at         the high side boundary in 1(a) and the low side boundary in         1(b). (For example, one may use a runner length of 1030 mm per         rack with a 20-denier non-elastomeric nylon yarn if the machine         gauge is ranged from 36 through 40 inclusively); and -   2. establishing the effective ranges of the runner lengths, in the     unit of millimeter per rack, of the elastomeric yarn, wrapped on the     warp beam(s) with 50% accumulated beaming stretch and fully threaded     from a guide bar at the rear side of the Tricot type warp knitting     machine, against the machine gauges, ranged inclusively from 28     needles per inch through 50 needles per inch, where:     -   (a) the yarn runner length at a high side boundary equals         3246×e^(−0.0456×(machine gauge)) with rounded off decimal; and     -   (b) the yarn runner length at a low side boundary equals         2399×e^(−0.0456×(machine gauge)) with rounded off decimal; and     -   (c) the ranges of the effective yarn runner lengths are laid         between the numerical solutions, with rounded off decimal, at         the high side boundary in 2(a) and the low side boundary in         2(b). (For example, one may use a runner length of 480 mm per         rack with a 40-denier elastomeric spandex yarn of 50%         accumulated beaming stretch if the machine gauge is ranged from         36 through 40 inclusively).

To manufacture the warp knitted fabrics of the present application, an operator may need to apply the techniques of:

-   1. establishing the effective ranges of the fabric pulling tension     immediately after the fabric being formed on the Tricot type warp     knitting machine, also known as the take-up tension, in the unit of     course per centimeter, against the machine gauges, ranged     inclusively from 28 needles per inch through 50 needles per inch,     where:     -   (a) the take-up tension at the high side boundary equals the         numerical solution, with rounded off decimal, of the product of         the positive rational number of “1.15” and the positive integer         number of the machine gauge being adopted, added by the positive         integer number of “16”; and     -   (b) the take-up tension at the low side boundary equals the         numerical solution, with rounded off decimal, of the product of         the positive rational number of “0.85” and the positive integer         number of the machine gauge being adopted, added by the positive         integer number of “12”; and     -   (c) the ranges of the effective take-up tensions are laid         between the numerical solutions, with rounded off decimal, at         the high side boundary in 1(a) and the low side boundary in 1(b)         (for example, one may use a pulling tension of 52 courses per         inch if the machine gauge is ranged from 36 through 40         inclusively).

After the knitting process, other subsequent processes such as degreasing process, thermal setting process, and dyeing process can be carried out.
